MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV ( that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Experimental Determination of Entanglement for Arbitrary Pure States

Shao-Ming Fei, Ming-Jing Zhao, Kai Chen and Zhi-Xi Wang


We present a way of experimental determination of concurrence in terms of the expectation value of local observables for arbitrary multipartite pure states. In stead of joint measurements on two-copy states needed in the experiment [Nature 440, 20(2006)] for two-qubit systems, we need only measurements on one-copy state in every single measurement for any arbitrary dimensional multipartite states, which avoids the preparation of twin states or the imperfect copy of pure states.
